To all 'whov n it may 3 7 Be it known that I, SAMUEL'DQBSEY GRIP? FITH,a citizen of the United States, residi at Curwensville', in the-count ofClearfiel a and State of Pennsylvania,

certainfnew and useful Im rovements in' Atmospheric Clothes Poun ers;and I do "hereby declare the followin elear, and exact description 0 theinvention, will enable others skilled in the art to .wliichljtappertains to make and use the l or washing clothes by a oundinfiaandatmospheric operation in whic a cup-s ped plunger is employedhavi adisk-valve depending from a perforate partition in the cup forcontrolling the inlet of the air therein at each upwardmovement of thecu it is found that while the disk valve is e ective for-closing theinlet of the'air and to cause the-air in the cup to be forced throughthe clothes by the pounding action, the diskvalve'is liable to beuncertain in its 0 ening function to allow the cup to be-filled withair. My 'im rovement is directed to means objection is overcome and thedisk-v Va is rendered certain in its opening function; and: also bywhich the. valve is caused to have an active pounding andagitati'nfimfunction upon the clothes, the valve t purpose beingprovided with one or depending plates movable with it and c aimsappended hereto I will set out arts and combination of parts wherein myimprovement resides in'connection with the accompanying drawings,wherein- Figure 1 shows-in vertical section an athaving my improvement,the air controllin ing in open position. Fig. 2 is an i eiitical aircontrolling valve being in closed position. Fi 3 is a' bottom view ofthe cup-pounder. ig. 4 is a bottom view of the plate-valve having ovalformed depending plates. I v

' bi i t e ac valve depending plates is tube 5, w 'ch extends 'to and isfixed to the cupl-partitionpins 7 and has a diameter adapted to inclosethe openings in the partition and is movable preferably with itssuspending pins for opening and closing the openings in the cuppartition to admit air into the cup as it is-raised and to cause the airto be forced into and through the clothes as the cupis driven upon them.Forthis purpose the valve suspending pins preferab y pass t partitionand the o ning movement of the valve is limited by t e heads of the pinsresting, upon the partition. Appended to and depending from thisplate-valve is one or more plates 8, 8, of less area than the valve, onebelow the other and preferably the lower ones of decreasing area, eachsuspended from and movable together with the yalve. That is to say, thedepending lates may each have a-fixed relation to the va ve and to eachother cup-chamber from the partition by headed hrough holes inthe bytheir suspending pins 9, 9. These'deplates may be of any suitable formpreferably havingcurved edges so as not to in ure the clothes. They maybe of oval form crossing each other at ri ht angles, but of-whateverform they each ave a separate pounding action upon the clothes and.aseparate suction action thereon in the lifting movements of the cup, andin this way the action of each plate reinforces the pounding function ofthe cup and-facilitates the washin and cleansing o ration of theclothes. ese valve depen ing plates have also a releasing function forthe plate-valve, that is, they render it certain by a pulling action onthe valve, caused byt e water to olpfinit on the lifting movement of thecup.
